Naayeeneizghani was called around 1897 or 1898.  She hailed from the Navajo people who settled near the future sight of Sunnydale.  Her watcher was killed by a vampire demoness type creature.  She trailed the demoness down to a small settlement above the hellmouth.  She wandered into a boarded up saloon owned by a man named Willy.  She walked through the darkened room and realized that the entire saloon was full of vampires hiding from the daylight.  Naayeeneizghani walked to the bar and asked where the demoness was and Willy tried to play stupid.  She ended up killing three vampires to refresh his memory of her status as slayer, then he revealed she was hiding upstairs.  Naayeeneizghani walked out of the bar and burned it to the ground, then shot the vampires who escaped the blaze.  There, the demoness was floating above the inferno, not surprised that the slayer found her.  Following a short fight, the slayer managed to stab the demoness in the heart with her broken bow, but not before being stabbed by the demoness.  Naayeeneizghani burned the settlement down and climbed atop her horse and she died.
